Hi all…haven’t posted much in a while but still checking in most days. I have a question that just leaves me scratching my head. 😁 I recently bought some fragrance oils and the IFRA rate for one of them is 10% for soap but 22% for lotion. How does this make sense? A wash off product has a lower usage rate than a leave on product.. Has anyone else ever seen this or have an explanation? Thanks for any input!
